JETMCONDENSER.

SPECIFICATION forming part of Letters Patent No. 387,261, dated August7, 1888.

Application tiled April 3, 1888. Serial No. 269,493. (No model.)

To all whom, t may concern.-

Be it known that I, Louis SOHUTTE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certainImprovements in Condensers, of which the following is a specification.

This invention relates more particularly to that class of jet apparatusemployed for condensin g the exhaust-steam from steam-engines and thevapors from Vacuum-pans for the purpose of creating and maintaining avacuum; and the object of the invention is tcmaintain a uniform anduninterrupted working of the apparatus, and this by preventing the usualaccumulation of air in the upper or receiving end of thecondensing-chamber. Io this end I provide the apparatus-which may be inall other respects of ordinary construction-with one or more isolatedpassages or conduits leading from the upper part of thecondensingchamber to the lower part of the condensingtube or otheradjacent part of the apparatus where a strong suction exists, the effectbeing to cause the air which may be set free from the steam or water inthe condensing-chamber to pass downward through my supplemental passageto the delivery end of the apparatus.

The apparatus represented in the drawings, with the exception of itsauxiliary passage,may be identical or substantially identical inconstruction and operation with those represented in Letters Patent ofthe United States issued to Corting October 2,1883, N o. 285,022, and toSchutte November 10, 1885, No. 330,157.

In the accompanying drawings, Figure l represents an elevation of acondenser having my improvement embodied therein,a portion of the bodybeing shown in section through its middle. Fig. 2 represents across-section of the same on the line x m. Fig. 3 is a central sectionalelevation of the apparatus in modified form.

Referring to the drawings, A represents the tubular body of theapparatus provided on one side with va throat or neck, a, through whichthe exhaust-steam is admitted to the interior space or chamber, a',commonly known as the condensing77 or steam-receiving chamber. At itsupper end the body is provided-with the neck b, through which the waterfor condensing purposes is admitted to the central water-nozzle, c.

B represents the combining-tube located cen-y trally within the body,its axis coincident with that of the water-nozzle. This combining-tubeis constructed as heretofore with a smooth central bore of uniform orpractically uniform diameter from end to end, and with a series ofinwardly and forwardly extending slits or passages, d, through which theexhaust-steam is admitted from the condensing-chamber into thecombining-tube, where it encounters the Water.

, C represents a central tapered ram or spindle adjustable endwise forthe purpose of regulating the area of the passages through thecombining-tube.

D represents a pipe for the admission of live steam when required toinaugurate the action of the instrument, or when under specialeircumstances it may be required to maintain the proper action.

The foregoing parts are substantially identical with those presented inPatent No. 330,157 above referred to,and are not claimed as of thepresent invention.

Vhen the apparatus containing only the above-named parts is operated,the exhauststeam,entering the chamber a', rushes in a forward directionthrough the slits or passages d, and encountering the water is condensedthereby, its impingemeut against the water serving to maintain thevelocity of the jet. Under the ordinary construction the air set freefrom the steam accumulates in the upper end of the condensing-chamber auntil its volume is such that it is carried along by impact ot' theexhaust-steam into the condensing-tube, the effect of which is todestroy the continuity of the current and momentarily disturb the actionof the apparatus. I therefore provide the apparatus with a passage tubeor conduit, e, leading from the upper end of the condensingchamber intothe lower end of the combiningtube or into this discharge-tube at anypoint where there is a strong suction, so that the air, as fast as it isset free and rises to the upper end of the condensing-chamber, will bedrawn downward through the passage e and carried with the outgoingcurrent at the delivery end of the apparatus It will be observed that myconductor is entirely isolated from the condensing or steamreceivingchamber, except at the upper end,

and that its effect is to prevent the air from passing into thecombining-tube, except at the lower or delivery end.

In Figs. I and 2 I have represented the pas- 5 sage e as east within thebody A; but it may be applied externally or in any other desired manner,and instead of a single passage there may be two or more passages oflimited area. In Fig. 8 I have represented two tubes, e, ro screwed intothe mouths of openings into the lower end of the combining-tube andextending thence upward within the apparatus to the upper end of thecondensing-chamber.

Having,` thus described my invention, what I r 5 claim is- In acondenserof the type herein described, an isolated passage or passagesleading from the upper part of the condensing or steam-receiving chamberto the lowerpart of the combining tube or chamber at or near the mouth2o of the discharge-passage.

In testimony wliereofI hereunto set my hand, this 6th day of March,1888, in the presence of two attesting witnesses.
